Analysis on Parameters Influencing Max. Stress of Inner Rubber of Elastomeric Bearing

Abstract:

In this paper, some factors effect on the maximum stress of inner rubber of some elastomer isolators with big diameter of 1500mm are analyzed by FEA. These factors include size of hole, ratio of , shear modulus of inner rubber , the first shape factor , thickness of cover rubber. The isolators include those used in building or bridge, loading condition is single compress . Research results show that size of hole, ratio of and have a little effect on the maximum stress of inner rubber, but shear modulus of inner rubber, and thickness of cover rubber hardly effect.
